Robert Schmidt 9882460607 Remove Mutexes in phy_stub_UE.c 
Various mutexes are present in the phy_stub_UE.c file. However, it will
only be run in a single thread; the multiple-thread implementation also
runs the higher layers concurrently, which leads to races and segfaults.
Therefore, remove these mutexes, as we don't need them.

A lock help during executing a timer event prevented such event from

logic of the timing loop and adding/removing code such that this dead
lock does not happen.

Robert Schmidt e956c17bf8 Rename NR_UE_list_t to NR_UE_info_t 
The name NR_UE_list_t is misleading: beyond being a simple "list", this
structure carries all/most UE-related MAC information. If at all, it is
a container for multiple lists. The next commit introduces a
NR_UE_list_t structure that organizes UEs in lists such that it is
easier to go through the UEs.

Robert Schmidt de2cf2393b Do not allocate CCE in nr_configure_pdcch() 
nr_configure_pdcch() allocates the CCE, but this is not wanted, e.g., in
multi-user scheduling, since it might not be possible to allocate the
CCEs for these UEs. This commit makes the following changes:

- remove CCE allocation in nr_configure_pdcch()
- remove coreset search in nr_configure_pdcch()
- add functions get_coreset() and get_searchspace() to retrieve coresets
  and search spaces easily
- in nr_fill_nfapi_dl_pdu(), add extra parameters for aggregation level
  and CCE indices and the searchspace and coreset of a UE, which might
  be different for each UE
- allocate CCEs manually in phytest, RA, and DLSCH schedulers
